Maxillary third upper molar coronectomy: case report

Abstract

Introduction: Extraction of third molars is one of the most commonly performed procedures in oral surgeries. The indications for this procedure are linked to caries disease, periodontal disease, pericoronitis, among others. Case report: Male patient, 49 years old, absent from comorbidities, referred for removal of the upper third molar due to difficulty in cleaning and bacterial plaque accumulation, on tomographic examination, proximity of the roots to the maxillary sinus, where it was opted for the contraindication of extraction due to great chance of oroantral communication and suggested coronectomy to resolve the case. Objective: The purpose of this article is to present a case report and discussion with the technique applied to a maxillary third molar at risk of oroantral communication, demonstrating the benefits of this procedure. Conclusion: Coronectomy is a widespread technique in cases where the third molar is closely related to the lower alveolar nerve, with chances of paresthesia. There are no reports in the literature of this technique applied to the upper third molar.
